PROCESS OF DYEING.

SPECIFICATION forming part of Letters Patent No. 703,122, dated June 24,1902.

Application filed October 18, 1901. Serial No. 79,146. (No specimens.)

To aZl, whom it may concern.-

Be it known that I, GUSTAVE DE KEUKE- LAERE, chemist, a subject of theKing of Belgium, residing at 3 Rue Imperiale, Brussels, in the Kingdomof Belgium, have invented certain new and useful Improvements in theTreatment of Textile Material on Oops, Bob: bins, Spindles, and theLike, of which the following is a specification.

The dyeing or other "similar treatment of textile material-such ascotton and wool on cops, bobbins, crossed bobbins, spindle rolls, andthe 1ikepresents considerable difficul ties, owing to the unequalpassage of the dyeing or other similar liquid through the materialcaused by the numerous passages formed by the interstices between thecops, 850., and the spaces due to the conical ends of the latter.Several arrangements have been devised for removing these disadvantages,but with unsatisfactory results. Among others, apparatus was tried basedon the arrangement of a special holder or seat for each cop; but thiscould only be used for dyeing one kind of cop. In other apparatus thecops or bobbins are placed in smallperforated boxesin which all theinterstices between the cops are carefully filled out withcotton-wadding or cottonwool or the like by hand by a skilled workman.The small boxes are then placed into a larger perforated box which isplaced in the dyeing-vat. This method has the disadvantage ofnecessitating the employment of as many boxes or apparatus of differentsize as there are different sizes of bobbins or cops to be dyed, andalso of yielding only indifferent results according to the greater orless closeness of the filling material in the different parts of eachbox, since the dyeing or other liquid under pressure passes more readilyto the places offering the least resistance, so that the dyeing or othersimilar treatment of the cops or bobbins in one box is not uniform.

The object of the present invention is to remove these disadvantages,and, further, to render it possible to dye cops or bobbins of all sizesin one and the same apparatus.

The invention consists, essentially, in simply arranging the cops orbobbins in the large perforated box in which formerly the separatesmaller boxes were placed and in filling the interstices and channelsbetween the cops with pulverulent material-for instance, sanduniformlydistributed by means of a current of water or other liquid, the saidmaterial being retained in the box by means of a porous mantle, such asa coverning for the inner walls of the box, which allows the Water orother liquid having served to distribute the filling material to flowoff, so that at the moment the perforated box is placed in thedyeing-vat the former practically consists of a solid block containingbobbins or cops cast, so to say, in a more or less plastic material,offering the same resistance to the dyeing liquid at all points.

In order to have my invention fully understood, I will now proceed todescribe the same, reference being bad to the annexed drawings, in whichFigure l is a vertical sectional view of a perforated box as ordinarilyused. Fig. 2 is a top view of the same, the cover being removed.

According to my invention a perforated box 1 is used, one of the facesof which (the cover) can be removed for. the purpose of introducing thebobbins or cops carrying the material to be dyed. This box 1 is placedfiat on the ground, for instance, and is covered inside with a cloth orother suitable filtering fabric 2, sufficiently large to leave pieces 3projecting on the four sides of the box. The cops or bobbins 4 are thenplacedin layers in the box side by side.

Then the box 1 has been filled in this man ner, it is necessary to fillup the channels 6 between the cops and also the spaces 5, formed by theconical ends thereof and the sides of the box. For this purpose over thecops arranged in the box, a certain quantity of sand, for instance, isthrown, and then upon the said sand a suitable jet of water is directed.The water carries the sand with itintoall the interstices between thecops, and thus causes it to fill up all the channels. After the waterhas thus automaticallyplaced thefilling material in position it flowsoff out of the box through the porous covering 2, the latter, however,retaining the sand in 'the box. Then the sand is no longer moved by thewater and forms a uniform bed on the surface of the uppermost layer ofcops or bobbins, thus showing that all intersticcs and spaces aresuitably filled, the overlapping parts3 of the covering are folded overthe upper bed and entirely close in the sand and the cops inside thebox. The latter is then closed by means of a perforated cover 7, (a partof which is shown, Fig. 1,) attached thereto in the ordinary manner. Thebox is placed in the dyeing-vat, and the dyeingor other treating processis executed in the ordinary manner,whereupon the box is removed from thevat and opened and the dyed bobbins or cops removed from the material inwhich they are embedded and simply washed to free them from anyparticles or grains of the said material which may have adhered to them.

Experience has shown that with this new method bobbins are alwaysuniformly dyed, and the serious disadvantages which the dyeing processesat present in use suffer from are no longer to be feared, since thecompression of sand in the interstices and channels between the bobbinsor cops is always absolutely equal at all parts of the box. It isobvious that the method described obviates the necessity of the numerousmanipulations required by working with small boxes and of the employmentof an inconvenient and expensive material. Further, no relation of anykind need exist between the size of the cops or bobbins and that of theapparatus in which the latter are placed.

What I claim is 1. The herein-described process of treating textilematerial such as cotton and wool on cops, bobbins, crossed bobbins,spindle-rolls and the like with a treating liquid consisting insubjecting the material to the action of the treating liquid whenembedded in a suitable pulverulent material.

2. The herein-described process of treating textile material such ascotton and wool on cops, bobbins, crossed bobbins, spindle-rolls and thelike with a treating liquid consisting in placing the material to betreated in a suit= able pulverulent material, subjecting the textilematerial embedded in said pulverulent through the pulverulent materialand the textile material, and removing after the treatment the textilematerial from the pulverulent material in which it is embedded.

i. The herein-described process of treating textile material such ascotton and wool on cops, bobbins, crossed bobbins, spindle-rolls and thelike with a treating liquid consisting in placing the material to betreated in a suitable box, throwing a certain quantity of pulverulentmaterial in the box, then directing a jet of water upon the saidmaterial whereby the said pulverulent material is carried into theinterstices between the cops or the like, then closing the boxcontaining the pulverulent material and the textile material, causingthe treating liquid to circulate through the pulverulent material andthe textile material, removing the textile material from the pulverulentmaterial in which it is embedded and finally washing the textilematerial.

5. The herein-described process of dyeing textile material such ascotton and wool on cops, bobbins, crossed bobbins, spindle-rolls and thelike consisting in subjecting the textile material to the action of thedyeing liquid when embedded in a suitable pulverulent material.

6. The herein-described process of dyeing textile material such ascotton and wool on cops, bobbins, crossed bobbins, spindle-rolls and thelike consisting in subjecting the textile material to the action of thedyeing fluid after having filled the interstices between the cops or thelike with sand, removing the textile material from the sand after dyeingand finally washing the dyed material in order to free it from anyparticles of sand which may have adhered.

7. The herein-described process of dyeing textile material such ascotton and wool on cops, bobbins, crossed bobbins, spindle-rolls and thelike consisting in placing the cops or the like in a perforated boxcovered inside with a filtering fabric, throwing a certain quantity ofsand in the box, directing a jet of water upon the said sand therebycausing it to fill up all the interstices between the cops or the likeWhile the water flows off out of the box through the filtering fabric,closing the box, dyeing in the usual manner in a suitable dyeing-vat;removing the dyed cops or the like from the sand in which they areembedded and finally washing the textile material, substantially asdescribed and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
